It's now possible to define ordering criterias for sub-items. It's also possible to set priorities for sub-items. This feature was started with 16.02 but was not fully completed and finally landed in 16.04. Doing this, we also simplified the set of criterias available to the editor.

Fields can now be assigned to a category from the Content Type management UI, again making it possible to organize fields for editors in relevant categories.

Name pattern support for Relation, Relation List and Selection Field Types¶

The Relation and Selection Field Types can now be used to generate content names and URL aliases. This improvement comes with improvements to the API and SPI layer, making it easier to use complex field data to generate a title or url slug.

The system information panel in Platform UI has been improved, and reimplemented in a new package, ezsystems/ez-support-tools. This change will make it easier to add custom panels to the UI, or customize existing ones.

This setting will be used by the default content view templates. It is recommended that you also use it in your own templates, so that the site's layout management is centralized. Examples can be found in the eZ Platform demo templates.

A grid sub-items view has been introduced in PlatformUI. It displays items as blocks, with a large icon, and can be toggled from buttons on the top left corner of the sub-items view.

As of the 16.04 release, the feature is only being introduced, and the icon is identical for all elements. This will change in the future, as can be seen in the JIRA sub-items epic.

More importantly, this has been done to make it possible to developers to extend the user interface in this way. By default, eZ Platform will provide a list view and a grid view but developer will then be able to add their own views for specific context, content type or sections that might have specific business logic.
